Abstract
Provided is an imaging system including a light source which emits light in at least a portion of a wavelength band of an excitation wavelength with respect to each of a first fluorescent material emitting fluorescence belonging to a near-infrared wavelength band and a second fluorescent material emitting fluorescence belonging to a visible wavelength band, a first image sensor that detects a first fluorescent image of the target in the near-infrared wavelength band, a second image sensor that detects the second fluorescent image of the target in the visible wavelength band, and optics to direct the first fluorescent image to the first image sensor and the second fluorescent image to the second image sensor. The optics include a dichroic film that directs light of the near-infrared wavelength band into a first optical branch and at least a portion of light of the visible wavelength band into a second optical branch, separate from the first optical branch.
